Our invention relates particularly to the adjust-ment of the relative positions of the stripper mean'sw'hereby they may be caused tocommence littingthe opposite sides of the 'form simnltaneously sothat there may be a j m'i'nil'nmnamount or cracking ot' the mold,

`when removing from the pattern, and

among .the objects ot our invention are to provide v means in 'a jolt stripper machine 1U Jor so 'adjusting the stripper mechanism that the two sides thereof will begin lifting the torni at the same timegto provide adjusting means. io'r the ystripper mechanism; to provide a novel y.f'orr'n of adjusting means for 'a machine of the character described; to improve upon the construction of the stripper mechanism; and such further objects, ad vantages and capabilities as will later more fully appear and as are inherent in the construction disclosed.

Our invent-ion further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawing and, while we have disclosed herein a r preferred form of our invention, we desire the same to be understood as illustrative only and not as limiting said invention.

In the drawing annexed hereto and tormingl a parthereof, Fig. 1, is a lateral elevation ot a jolt stripper machine showing the location of our adjusting means; Fig.l 2 is an end elevation 'of this machine showing the relative positions of the co-operating stripperV pistons; Fig. 3 is a fragmentary elevation of a portion or" the mechanism shown in Fig. 1; Fig. 4 is an edgeview of the mechanism in Fig. 3; and Fig. 5 is a view similar to Fig. 3 showing a modified form of adjusting means to be used, if desired, in substitution for that shown in the other gures.

Referring more in detail to the annexed drawing, numeral '1 designates generally the body of the jolt stripper machine which is preferably mounted upon wheels 2 for ease in transportation'trom one location to another. At the .top of the body'is a table 3 upon which the pattern is placed when it is desired to pack .the sand around the pat- 50 tern. In use, the form is also placed upon this table, surrounding the pattern, and sand is then lled in between the `pattern and form as isunderstood by those experienced in this art.

At opposite sides of the table 3 are located the stripper pistons 4 yand 5 having 'stripper heads 6 and 7 -by means orn which the mold is vliitedv from the pattern after the sand has been packed around the latter. A shai't 3 is mounted in bearings 9 upon the mach-ine and carries vadjacent its OPPO- site ends va pair of crank arms 10 and 11. rhese crank arms are pivotally connected at 1Q to Vthe lin-ks 13 and 14 which are in t-urn pivotally connected at 15 to the stripper heads 6 and 7.

.lhe link 13 is provided in its lower end with an openii'ig 16 for the reception of an adjustable block 17 having therein an opening 18 for the reception of the pivot connecting` the crank arm 10 and the link 13. The sides or the opening 16 are formed as slideways for the block 17 so that the same will be properly guided and held in position therein. An adjusting bolt 19 has screw threaded engagement with an opening in the arm 13 and is locked in position by means of a locknut 20. The head of this bolt engages one face of the block 17 and a similar bolt 21 engages the opposite face thereof, as shown in Figs. 3 and 4. The bolt l21 has a locknut 22 which engages the cross-head2?) to hold the bolt in adjusted position.

Instead of the construction described above the block 17 may have inclined sides 24 as shown in Fig. 5 and blocks 25 having similarly inclined sides therewith to move the block 17 upwardly or downwardly as desired, when the bolts 26 are properly manipulated. These bolts will be held in position by lock nuts 27 or other desired securing means. The crosshead 9.3 is'secured in place by bolts 28 or other suitable means.l p

VFrom the construction described above, it will be apparent that the stripper heads 6 and 7 may be relatively adjusted, vertically,

will co-operate it possible to cause the stripper mechanism to begin lifting on opposite sides of the form at the same time. Fiom the foregoing it will be seen that We have provided a novel means for accomplishing the objects herein specified.

Having now described our invention, We claim:

l. ln a machine of the character described, having pattern supporting means and means movable to strip a mold from a pattern, said last named means comprising a plurality of separate parts engaging the mold supporting' ferm at separated points, independent hydraulic means for operating the said separate parts, means for preventing one side of the stripping means from advancing` more rapidly than the other, and means for relatively adjusting opposite sides of said preventing means.

2. ln a stripping mechanism, reciprocable stripping means, independent hydraulic means on opposite sides of the machine for operating the stripping means, mechanism for controlling the functioning of the stripping means so that opposite sides will operate synchronously, and means for adjusting the last named means to cause. opposite sides of the stripping means to begin functioning at the same time. e

3. ln a stripper mechanism, a table,stripper lpistons on opposite sides thereof, links and connecting means therefor4 to synchroniZe the movements of the stripper pistons, and means for adjusting` the relative heights of the pistons.

e'. In a jolt stripper machine having a table, independent stripping members on opposite sides thereof, means to raise the stripping members, and means connecting the raising means so that they Will operate synchronously; an adjustable trunnion oining the stripping-member raising-means and the connecting means, and adjusting means whereby the trunnion may be adjusted to cause the stripping members to begin func- `ticning simultaneously and tooperate synchronously.

ln Witness whereof, We hereunto subscribe our names to this specification.
